Contractors must handle all waste disposal in compliance with federal, state, and local regulations.

The estimated annual spend is $97,040. The contract term is three years with City options to renew for up to two additional consecutive one-year terms. Contractors must have a minimum of five years' experience performing UST fuel sampling and biocide treatment and provide a 30-day warranty against microbial reoccurrence. Required insurance includes Commercial General Liability of not less than $1 million per occurrence and Workers' Compensation meeting North Carolina statutory requirements.

The Non-Mandatory Pre-Proposal Conference is scheduled for August 10, 2026 at 2:00 p.m. EST via Microsoft Teams. Written questions are due August 4, 2026, with follow-up questions due August 14, 2026. All proposals must be submitted electronically through the Bonfire e-Procurement Portal. Contractors must register with the City's vendor registration system, comply with E-Verify requirements, and meet state restrictions on contracts with companies that invest in Iran or boycott Israel. The contract will be awarded by City Council following evaluation.
